SPECIFICATION forming part of Letters Patent No. 634,306, dated October3, 1899.

Application filed September 21, 1898. Serial. No. 691,516. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS F. MORRISSEY, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and usefullmprovementsin Button-FinishingMachines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters and figures of referencemarked thereon, which form a part of this specification.

The objects of this invention are to facilitate the work of polishing orbuffing or otherwise finishing the buttons and by applying them morequickly and regularly tothe polishing-wheel to reduce the cost ofmanufacture, to secure a more uniform product, to dispense with the useof hand labor to a large extent, to secure the buffing effects bymechanical means only, and to secure other advantages and results, someof which may be referred to hereinafter in connection with thedescription of the working parts.

The invention consists in the improved button making or finishingmachine and in the arrangements and combinations of parts thereof, allsubstantially as will be hereinafter set forth, and finally embraced inthe clauses of the claim.

Fig. 55 is a plan of a pair of levers for operating orcontrolling a certain slide of the chuck, the said levers beingcontrolled in turn bythe cam of Fig. 3; and Fig. 56 is a front view ofthe same.

In said drawings, a, Figs. 1 and 2, indicates a suit-able frame arrangedon standards or studs Z) b. At one side of the said frame is arranged abufling or finishing wheel 0 and suitable means for rotating the same,such as the belt and pulley c c, Fig. 1, and at the opposite end isarranged a feeding mechanism comprising a receiver (1, means for arranging the buttons in a series or succession, means for feeding themone by one to a hopper p, and an oscillating button-transferring arm orcarrier f, adapted to take the button from the said hopper and place itupon the chuck at the upper extremity of a second oscillatory arm 9. Thesaid second vibratory arm 9 comprises a lever 72, fulcrumed at 1' uponsaid standard Z) near the lower end of said standard, and a spindle S1for rotating said chuck as the arm it oscillates. Said arm it is givenoscillatory reciprocations by a cam 7' (shown in Fig. and a canrgroovej,which receives the trundle j formed or arranged upon the rear side ofthe lever, as shown in Figs. 1 and 3. The lever-like reciprocatingchuck-arm IL is given a movement sufficient to bring the upper end ofthe chuck 'r from a point where it receives the buttons from the carrierf to the peripheral face of the buffing or polishing wheel 0 and fromthence to a point where it enters into engagement with stripping meansfor removing the said buttons from said chuck and causing them to passdown a suitable way or chute 112 to a receptacle for the finishedbuttons.

lVhile I have shown in the drawings a detail construction by which Iaccomplish the results desired, I do not wish to be understood aslimiting myself thereto, for I am aware that various modifications ofconstruction may be employed withoutdeparting from the spirit or scopeof the in vcntion, and consequently I do not wish to be understood whendescribing the parts in detail hereinafter as limiting myself by thepositive expressions and descriptive terms employed excepting as thestate of the art may require. With this understanding I proceed todescribe in detail the peculiar arrangements of parts by which I effectthe automatic or purely mechanical polishing of the button.

In describing the detail construction I prefer to follow the course ofthe button through the machine to enable a better understanding of suchconstruction to be obtained.

The unpolished or partly-finished buttons are first inserted in largequantities in the receiver (Z. This receiver and the parts immediatelycooperating therewith are somewhat similar in general construction tothe one shown in the feeding device of the button-machine shown in myprior patent, No. 547,561, dated October 8, 1805. In my said priorpatent the receiver was an open hopper. In the present construction thereceiver comprises a spun sheet-metal case (1, the sides of which flaretoward the back of the machine and which at its rear edge is providedwith a flange by means of which it is fastened by suitable screws orotherwise to a rear plate Z, rigidly secured upon the arm a of the frameof the machine. The said plate Z is inclined, as in my priorconstruction. The forward part of the said case (1 is open, and theopening is closed at the lower part by a glass plate (1 and at the upperpart by a hinged door (7/", the glass plate serving to permit an easyinspection of the interior of the receiver, while protecting the buttonsfrom lint, dust, &c., produced in the polishing operation, the said dustif allowed access to the buttons being detrimental to a proper feedingoperation in that it tends to clog the parts and prevent the desiredautomatic 0pcrations.

At one side of the receiver (Z the same is open or slotted, as shown inFig. 1, and through the slot the notched periphery of the rotary disk atprojects. The said rotary disk on is similar in construction to the oneshown in my prior patent, it being also provided atits center withradial ribs (shown in Fig. 14:) for facilitating the turning of thebuttons and causing them to properly enter the edge notches, and thesaid notches serving to receive the buttons, arrange them into a series,and feed them regularly and uniformly to the feeding mechanisms outsideof the receiver.

. The buttons entering into the notches the same are carried upwardlywithin the receiver and thence down-into the slot in said receiver, andfrom thence the said buttons are fed to the cooperating feeding devices.

The inclined plate-Z, upon which the notched disk m rotates, is providedwith a raised margin Z, and said margin outside of the receiver-caseserves to hold the buttons within the notches, and a spring guide orkeeper 5, Figs. 1, 12, and 14, is arranged in front of the notches ofthe periphery of the disk outside of the said case, also to hold thebuttons in place within said notches. The raised margin Z of theinclined plate at the point from which the buttons are to be fedtherefrom is provided with an opening 6, as shown in Fig. 12, throughwhich the buttons pass out automatically by gravity upon the inclinedWay or passage 7, formed on the upper face of a bracket 8, when said wayis not obstructed by another button lying on said way or by a cut-01fgate 9, lying at said opening, or by an antijamming stop 44, hereinafterto be described.

In my prior device the out-passage opening 6 for the buttons was formedbetween end walls of the raised rim Zof the inclined plate. At thisopening was arranged a spring to prevent jamming; but notwithstandingthis spring the buttons when not properly fed were apt to catch orjam,thelimited elasticity of the spring being insufficient to prevent thetrouble and in some cases occasioning a damage to the button.

To more perfectly avoid the possibility of injury to the button, I havein the present construction arranged at one side of the button-egressopening 6 of the receiver a movable piece 12, which supplements theraised margin, and being hinged or pivoted at 13 to the end 110 of theraised margin Z extends in the curved line of the said margin to a pointabout midway of the opening, where at its free end it receives a secondhinged piece 14, which latter is raised above and away from the plane ofthe rib or raised margin Z and supplemental piece 12 to permit of-thepassage of the button beneath. The hinged piece 14 is pivoted to thebracket 8 at 15, Fig. 20, outside of the upper end of the margin Z, andat its opposite or lower end it is loosely linked to the piece 12, asuitable slot 160 being provided in oneof said pieces to permit of thedesired knuckle action. The hingepiece pin 18 works in said slot andholds the pieces together at their free ends.

The buttons are permitted to pass between the upper end of the margin 1and the end of the supplemental piece to enter into engagement with apocket-stop for preventing a direct passage of the button into thehopper the button.

beneath; but should the button because of some abnormal movement orother condition fail to pass through said opening 6 and tend to becomejammed in said opening to the injury of the button the abutting free endof the supplemental piece, being only held in normal position by aspring 20, gives under the pressure of the button to prevent injury andsets a train of devices into 0pera-' tion by which the button isimmediately returned into its notch in the periphery of the disk d.

Under pressure of the button, as described, the pieces are forcedoutward and operate a cam-arm 21, which, pivoted upon the hingepin 18and extending through the slot 16, Fig. 17, receives the spring 20. Thesaid cam-arm when pressed, when the pieces 12 14 are pressed out by thebutton, is caused to engage a SllClfiOl'pIGSSUPG-PlGCG 19 with anelastic pressure due to the spring 20, and this pressure is sufficientto overcome the pressure of the spring 49 of thepressure-piece andeffect a lengthwise movement of said pressure-piece at its slotted end.(Shown in Figs. 20 and 28.) Said pressure-piece at its end opposite thatengaged by the cam-arm is pivoted upon the short arm 45 of the leverlikestop or cut-off arm 44 and causes said arm 44 to turn on its fulcrumalpin 40,which is preferably removable, and throw its free longer armdownward into the opening 6 to stop the progress of the button outthrough said opening, holding said button so that the continued movementof the disk and the bearing at the end of the piece 12 throws saidbutton back into its notch in the disk before injury by jamming isreceived. Under normal conditions, however, the button is permitted topass through the opening 6 onto the slideway ot the bracket 7, attachedto the receiver; but here its downward gravitation over the inclinedslideway is almost immediately stopped by another cut-off or stay 38,hereinafter more fully described.

. To secure a more perfect control of the feeding of the button and topermit of a normal out-passage of the said button from the receiver onlywhen the way is prepared for the same, I provide button stops, gates, orcutoifs, which are controlled by the slide 19 and cam part 21. The firstcut-off of the series is the gate 9. This comprises a hooked piece whichis pivoted at the back of the receiverplate, as indicated in Figs. 14and 15. The said gate 9 receives its motion from the upward extension 23of the slide 22, the said slide having bearings in the bracket 8 andengaging the shoulder or bearing 24 of the said gate and pressing thehooked end inward toward the opening 6, the extremity closing the same,so as to prevent the out-passage of The said slide 22 and its extension23 are reciprocated by the arm 27, Figs. 1, 12, and 15, pivotallyfastened upon a second slide 28, arranged in bearings in the frame a andthis slide in turn is reciprocated by a leof the extension 23 isremoved.

ver 29, fulcrumed at 281 on the bed or frame (I, and extending downwardto the cam j,where the lever-arm of said lever engages a cam projection291, Fig. 1, to receive its reciprocatory movement in one direction. Toreceive the return movement, the lever 29 is in connection with acompound lever 31, the members of which are hinged together at 32, thesaid compound lever being pivoted to the lever 29 at 33, and uponsuitable fulcrum 34c, near the foot of the standard I). The lever 3tcarries the trundle 35, which engages a camsurface 36 upon the cam j, bywhich means or by any other means desired I secure an OS- cillation ofthe lever 29 and reciprocating sliding action of the slide BSand acorresponding reciprocation of the arm 27 and slide 22, by which thegate 9 is alternately opened and closed, the parts being timed toprevent a second button issuing from the receiver while a first one ison the slideway.

Then the gate 9 is closed by the pressure of the extension 23 againstit, it is done so against the pressure of a spring 37, Figs. M and 15,which latter opens said gate 9 a limited distance automatically when thepressure The opening of the gate 9 permits an out-passage bygravity ofthe button from the notch in the disk then coinciding with the opening6, the button passing out through said opening 6 upon the inclined way 7of the bracket 8.

The bracket 8 is provided with lugs or bearings 39 39, Fig. 12, whichare perforated to receive a removable pin -tO, upon which latter,between said lugs, is pivoted the said cutoff or stop device 38. Thebody of said outoff device consists of an irregular piece of metalhaving a fulcrumal bearing to receive the pin 40 and fit between thelugs 39. Said body is bent at one end to give to said body a crankshape, the bent extension 41 serving to receive and be operated by abearing 42, Fig. 20, of the arm or extension 23 of the slide 22 when thesaid extension closes against the gate 9, the bearings 23 and 42engaging, respectively, the gate 0 and the extension 41 simultaneously,or approximately so, thus closing the opening 6 to prevent theout-passage of a button and raising the body 88 of the cut-off from theface of the slideway 7 to permit the button lying back of the saidoutoff body to drop into the hopper p. At the back of the said cut-offbody 38 the same is provided with a suitable downward projection orformation 3811, Figs. 28 and 29, which serves as a stop or pocket forthe down wardlymoving button, and is also provided with anadjusting-screw 4-3 for regulating the distance of pivotal movementtoward the slideway 7 of the bracket. The body 38 of the cut-off not theengagement of the bearing 42 with the arm 41 of the cut-off body 38 thesaid outoff body 38 is raised from the way 7 and the button beneath isallowed to drop or slide down said way into the hopper p, where it isturned to lie substantially at right angles to its former position bystriking the inclined wall of the hopper as it drops. The bottom of saidhopper is slotted to permit the outpassage of the button, the bottomopening being controlled by a slide-valve 50, which is kept normallyclosed by a spring 51, Fig. 12, the said slide-valve working in asuitable slideway or bracket 52, attached to or formed 011 the hopper.The opening or passage at the bottom of the hopper is made large orsmall to suit the differently-sized buttons by means of an adjustableplate 54-, arranged within. the hopper and controlled by suitableadjusting-screws 55 50. At its forward end the said slide or valve 50 isprovided with a downward projection 53, adapted to be engaged by anoscillating button-carrierf. Said button-earrierf is adapted tooscillate between the hopper p and the button-chuck 1' when the latteris in its button-receiving position, so as to receive the button fromsaid hopper and carry it to said chuck, by which latter the said buttonis presented to the polishingwheel 0. Said carrier f is operated by theslide 28, which latter is provided with a rack 57 to engage a pinion 59,having a pivotal shaft or hub (50, with bearings in the frame of themachine. Said shaft or hub 60 moves with said pinion and has the body ofthe carrier fixed thereon, so that said pinion, hub or shaft, andcarrier are adapted to oscillate together as the slide 28 isreciprocated by the lever 29, as above described. Said carrier ispreferably adjustably fastened upon said shaft or hub (30. A set-screw61 fastens the carrier to the hub and permits the desired adjustment.Said carrierfcomprises abodyplate (52, to the under side of which isattached or formed a lug 63, providing bearings for the hub andset-screw G1, which lug is formed at the lower end of the said bodyplate(32. At the opposite free end of said body-plate 62 means are providedto receive the button as it drops from the hopper and to hold saidbutton firmly in place at said free end while the carrier makes anoscillation or turns over upon the chuck, the operating parts beingtimed in their movements, so that the button will be placed in positionat the said free end of the chuck by said carrier, the button beingforwarded by said chuck to the periphery or polishing-surface, as beforedescribed.

Upon the upper face of the reciprocating body-plate (32 are pivoted uponthe pin or screw (331 the shear-like grasping-fingers 6t 64, having attheir free ends curved flanges 05 05, which together form a pocket orreceptacle for the button as it slides from the hopper over the body-plate of the carrier, the up per ends of said flanges being separate,as in Figs. 13 and 37, so that when the fingers are spread a passage ofsufficient width for the button will be formed, the lower end of thecurved flanges serving as stops, preventing further passage, as will beunderstood.

The said flanges are undercut or inwardly shouldered, as at 651 in Fig.35, to hold the button in place between the flanges when the fingers areclosed and are more or less funnel-shaped or flaring on their concavesides to serve as guides for the chuck to bring the latter into a properrelation to the button when the carrier is turned down upon said chuck.Said flanges are preferably removable from the body of the fingers topermit of an interchange of flanges to suit different sizes of buttons.

The fingers 64 are normally held together by a spring 66 and are spreadapart so as to permit the entrance of the button from the hopper by alever67, Figs. 12, 13, and 34, which is fulcrumed at 68 upon the underside of the body-plate 62 and passing at one end through a slot in theplate 62 is made at its extremity wedge shape, and is thus adapted toenter between the said fingers 64 64 to spread the same apart. Saidlever 67 is operated by engaging at its opposite end a trundle 69,arranged on a short stud in connection with the slide 28. As the saidslide moves forward with the trundle it turns the pinion 59 in thereverse direction and causes an engagement of the lower arm 671, Fig.12, of the lever with the said trundle 69 and a movement of the carriertoward the hopper and at the end of the movement an engagement of thecarrierplate with the projection 53 of the hopper slide, gate, or valve50, throwing the latter open simultaneously with the opening of theflanges 65 to permit a passage of the button therebetween. Then thefinger-flanges are closed against the button, the latter is pressed alittle forward against the shoulders 651 by a pressure-plate 70, Figs.35, 39, and- 40.

At a point near the free end of the carrier in coincidence with thechamber or aperture between the flanges 65 I have formed an opening forthe pressure-plate above referred to. Behind the plate 62 at saidopening I have arranged a short cylindrical pocket 71, Figs. 12, 34, and35, in which is arranged a spring 72, Fig. 35. The pressure-plate 70 isprovided at its back with another cylinder 73, which workstelescopically in said cylinder 71, the spring 72 lying at one endwithin said cylinder and at the other against the bottom-of the pocket71. At the center of said pressure-plate at the back and within saidcylinder 73 is formed a shank 74, which extends back through aperforation in the bottom or end of said cylinder 71 and thereatreceives a crank-lever 75, fulcrumed upon a stud 76, Figs. 34 and 36,one arm of said lever being loosely pivoted to the outer end of theshank 74 and the other arm providing a bearing for the long spring 77,which last is adapted to engage a bearing 73, Fig. 12, upon the frame ofthe machine as the button-carrier approaches in its return movements thehopper p. The said spring 77 is of sufficient strength to counteract thepower of the spring 72, and is thus adapted to press the pressure-plate70 back to a position flush with the face of the bodyplate 62 as thebutton grasping or holding fingers 64 are spread apart by action of thelever 67 The button being released by the opening of theslide 5Ogravitates from the hopper onto the plate 62 and enters between thegrasping-fingers 64 and over the plate 70, the edges of the buttonentering beneath the undercut shoulders formed at the inner edges of theflanges 65. between the fingers by gravity, the graspingfingers firstclose upon the edges of the button and start with the carrier in'itsoscillation toward the chuck. Almost immediately the spring 77 passesfrom engagement with the bearing 73 and permits the spring 72 to forcethe pressure-plate 70 forward against the face of the button, clampingthe latter against the sides of the flanges. The carrier continuesitsmovement until the button is brought into contact with the chuck,where said button is caught and held by said chuck in a manner which Iwill now proceed to describe.

Upon one of the studs or standards 1), near the base thereof, isfulcrumed the oscillating chuck-carrier h. This is given its oscillatorymovement, by which the chuck is caused to travel the face of thepolishing-wheel, by the cam j, which last is provided wit-h a camgroove79, Fig. 1, the said chuck-carrier being provided with a suitable pivotj, upon which is arranged a trundle 80, which latter works in saidcam-groove, as will be understood. The said lever-like chuck-carrier isprovided at its upper free end with bearings 71 h h h 71 for a spindle81, its sleeve 82, and a spindle-worker 83 for giving longitudinalmovement to the spindle, as shown more clearly in Figs. 41 and 42. Saidsleeve 82 carries the pulley 84, by means of which said sleeve is givenits rotary movement. Within said sleeve it is provided with a suitablekey, feather, or spline 85, which works in a longitudinal groove 86,formed in said spindle. The said spindle is thus caused to rotate withthe sleeve and at the same time is permitted a longitudinal movementindependent of said sleeve. The lower end of the spindle 81 is looselycoupled to the non-rotary spindleworker 83, and the latter is given atsuitable times the desired longitudinal movement by means of a system oflevers, hereinafter described, operated upon by the cam j-or by any.other suitable means. At the upper end of the said spindle 81 isarranged the check '1', which latter is thus given bot-h an oscillatorymovement, by means of which it'is caused to traverse the space betweenthe carrier f and stripping devices, a rotary movement, whereby thebutton is rapidly turned as it traverses the polishing-surface of thewheel The button having entered ICC c, and a longitudinal movement, bymeans of l which the said chuck is raised and lowered toward and fromsaid wheel after having received the button from the oscillatingcarrier. The said chuck is shown more clearly in detail in Figs. 11- to52. The upper end of the sleeve 82 is provided with a flange or bearing87, and the upper end of the spindle 81 is threaded, as at 88. Upon saidupper end of' the spindle is screwed the body 89 of the chuck, thelatter being provided with suitable female threads 801 to receive thesame. Around said body portion of the chuck is arranged a sliding collar00, which has a limited sliding movement. Said sliding collar 90 isprovided with a key 90l, which works within a transverse slot or grooveS02, Figs. 18 and 49, formed in the chuck-body, by means of which keysaid collar is prevented from turning on said chuck-body. Said collar isnormallyheld at its upper limit of movement on said body by a spring 01.

\Vithin the slot 802 is arranged a sliding block 92, which is suitablypinned to the sleeve 90 by the key 001', so as to slide therewith. Saidblock 02 is centrally apertured, the aperture 0 3, Fig. 47, havingrounded or inclined side walls and opening at the upper end of the blockand receiving a pair of crossing or shear-like levers 01 and 95, Fig.11, which are pivoted or fulcrumed together at 06 and at their lowerextremities are arranged within said aperture .13. The upper oppositeends of said shear-like levers are provided with the pintles 07, adaptedto enter within the holes or eyes of the button when nearest oneanother. Between the lowerends of said levers I interpose a spring .18,so that said lower ends or arms have a normal tendency to be spreadapart and the upper ends closed together. Thus when the collar 00 islowered by means hereinafter described the said levers 91 95 will bespread apart at their lower ends by the springOS and the upper pintleswill be brought toward one another to enter the buttonholes, and whensaid collar 90 is relieved of downward pressure and the spring 91 isfree to press the same upward the opposite bearings 930, Fig. 4.7, ofthe block 92 will engage the roundings 0r inclines 90 00 of the leversand press the lower ends thereof together against the power of thespring 98, so that the pintles 97 will be thrown apart against the wallsof the buttonholes to clamp the button in position upon said pintles.

The collar 00 is pressed down so as to receive the button by a compoundlever 100, Fig. 1, which is fulcrumed at 101 and 102 and has its memberspivoted together at 103. Said lever is operated by the cam-wheelj, thecam grooves or projections of which are timed to cause the forked upperend 101 of the lever, as indicated in Figs. 55 and 56, to engage thecollar to press the same downward against the spring 91 when theoscillating button-earrierf is in position to receive the button fromthe feeding devices.

The rotation of the chuck while the latter is in engagement with thebutton-carrier f lengthwise of its axis of rotation, so that the buttonis raised at one end of the oscillation to the polishing-wheel andlowered when near the button-carrier f, I employ means for operating thespindle-worker 83, comprising an adjustable lever 105, Figsl, 4-1, and12, which is fulcru med upon a shaft 106, having hearings in an arm orbracket 107 at or near the bearing h formed or fixed upon the arm orlever ll.

Said lever 105 is in turn operated by cam pro jections upon thecam-wheelj. The said lever 105 is linked at 125 to the spindle-worker83, so that as the lever turns upward on its fulcrum the worker andspindle are raised with it. The arm 108 of said lever 105 serves toraise the spindle and the chuck thereon upward in a position to receivethe button, and the arm 10) serves to raise the spindle to bring thechuck into engagement with the polishingwheel. Said arms are providedwith suitable wheels to engage cam-surfaces therefor on the cam j, saideamsurfaces being suitably formed to secure the desired results. Afterhaving been raised by the means described and after having traversed theperiphery of the polishing-wheel the chuck continues its course awayfrom the feed mechanism a limited distance into engagement withstripping means for removing the button from said chuck. The take-offdevices or stripping means are shown in detail in Figs. 1 and 5 to 11,where 111 indicates a fixed fork attached to the chute 112, which servesto receive the sliding collar and press the said collar downward as saidcollar engages the inclined or curved bearings 113 of said fork near theend of oscillation. As the said collar enters into engagement with thesaid fork the chuck, where it is provided with the pintles, passes intoengagement with a pair of spring-actuated stripping-fingers 111 114,Figs. 9 and 10, which enter beneath the button and force the same freetherefrom, so that the said button is caused to slide into the chute,from whence it is directed to a suitable receptacle below. Saidstripping-fingers 114 are held together in proper relation to receivethe chuck and button by a spring 115.

A suitable guard 116 is provided to prevent the button from being thrownfrom the chute when released from the chuck.

To permit a free oscillation of the chuck carrier-arm when transmittingrotary motion to the chuck-spindle, I have provided a pair of idlepull'eys 117, asshown in detail in Figs. 5-3 and 54-, which serve inconnection with the belt which actuates the pulley 84. Said pulleys arepivoted, as at 118,-npon a slide 119, arranged in a suitable slideway120 of a bracket 121. As the oscillating chuck-carrier moves backwardand forward, as above described, the slide 119 correspondingly slides inits ways, the spring 122 holding said slide in proper relative positionand maintaining a uniform or approximately uniform tension upon thebelt. By pivoting the pulley-carriers 123 said pulleys 117 are permittedto oscillate in correspondence with the oscillation of the chuck-carrierand the pulley thereon, all as will be understood.

The movements of the chuck carrier-arm h are cushioned by a spring 124:.The lever 105 of said arm his adjusted by means of an adj Listing-screw126, which is threaded and adapted to engage the cogged extremity ofsaid arm 105, so that said arm 105 may be raised or lowered a greater orless degree, so as to bring the chucks in their operations nearer to orfarther from the operating-wheel, the said adjusting-screw thus beingadapted to bring the said chuck up -to the face of the polishing-Wheelas the latter wears away.
